What is the meaning of the following traffic sign?

- No parking of vehicles, except for the purpose of passenger unloading.
- Correct answer: End of cab rank.
- No stopping and parking for any other vehicle.
- Cabs are prohibited to stop and unload passengers beyond this point.
Why this is the answer
The correct answer in the official bank: End of cab rank.
A black diagonal band across a sign marks the end of the zone where the original sign applies. The original sign marks a cab rank, where other vehicles are restricted from stopping. With the black band, it tells you the cab rank ends here, and normal rules apply beyond it. It does not introduce a new stopping or parking ban.
